Eaton Cutler-hammer 10250T26R Momentary Push-button Switch

Product Description

The EATON CUTLER-HAMMER 10250T26R is a momentary (MO) push-button switch with a normally closed (NC) contact configuration, rated for 0.5 amps at 120 volts AC/DC. It features a red, round, extended mushroom-head operator made from zinc, with a non-illuminated design. Built for demanding industrial environments, this switch carries NEMA 4X, 4, 3R, 3, 13, and 12 ratings, making it suitable for oiltight, watertight, and anti-corrosive applications. It is installed by licensed electricians and industrial maintenance technicians in control panel and machinery applications where a normally closed momentary switching function is required.

This switch is well-suited for use in industrial control circuits, machine guarding, emergency stop supplementary controls, and operator interface stations. The momentary NC configuration makes it appropriate for circuits that require a break-on-contact operation, such as interlock or signal-interrupt functions in manufacturing, process control, and heavy equipment applications. Its robust NEMA ratings support use in wash-down, outdoor, and corrosive-atmosphere environments where standard switches would fail prematurely.

Compatibility

Designed as an OEM-style replacement or new-installation push-button switch for industrial control panels and operator stations requiring a NEMA 4X-rated momentary NC switching element.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC Article 430 or the applicable local electrical code. Disconnect and lock out all power to the control panel before removing or installing the switch. Verify the contact configuration and circuit function before restoring power. The mushroom-head operator profile requires adequate panel cutout clearance - confirm panel thickness and cutout dimensions against manufacturer documentation before mounting.
